Summary of the verification tests conducted by RAIMS Goal: Evaluate technology for monitoring the fatigue degradation of bridges Testing period: July-August 2015 Testing summary: Acceleration test to recreate the process of fatigue degradation of bridge decks
in simulation, using an actual-size bridge deck
and heavy load equipment (weighted wheeled testing apparatus).
Hennepin County (Minn.) approval of such specification allowed construction crews to remove and replace the entire 1,000 feet of the Franklin Avenue Bridge deck

Bonding between pavement layers is an important factor for long term performance of asphalt concrete (AC) pavements and for the durability of bridge deck
Optimum design of FRP rib core bridge deck

He said: "We are moving into a really exciting phase of the bridgebuilding programme now as work is progressing in the river on the main pylon foundations, and the panels for the bridge deck
